AUTOMATIC SPRINKLING AND FIRE-ALARM SYSTEM.

Application filed March 11,

To all whom it may concern:

Be it known that I, CHARLES A. JACOBY, a citizen of the United States, residing in Chicago, in the county of Cook and State of 5 Illinois, have invented a' new and useful Improvement in Automatic sprinkling and Fire- AlarmJ S stems, of which the following is a @ecificition.

My invention relates to improvements in re. us for buildings.

he object. of my invention is to provide an automatic, electric magnet valve controlled, thermostatic, sprinkler and fire alarm system and apparatus for buildings,

of a simple, efficient, safe, reliable and durable construction, in which the valves may be electricall operated by magnets or solen-' oids include in electric c rcuits having thermostatsffor automatically closing the circuits by arise of temperature, and to 0 en the same and close the valves by a fal of temperature, and in which the valves may also be opened or closed by hand, and in 26"which the e'fliciency" and operativeness of the apparatus may be at any time tested without danger'of flooding or injuring the building or its contents, and in which the action bf the ap aratus and each and every 30 circuit portion t ereof may be indicated or recorded.

My invention consists in the means I cinploy to practically accomplish this object or result. That is to say, it consists in the novelconstructionof parts and devices and in the novel combinations of parts and devices thereinshown or described.

-In the accompanying drawings forming a part" of this specification, Figural is a per- 0 spective view partly in vertical section of a sprinkler and fire alarm system embodying my invention. Fig. 2 is a diagram view of the apparatus illustrating the electric circuits. Fig. 3 is a detail vertical section through one of the electromagnet valves.

Fig. 4 is a detail section on line 44 of Fig.

valves D, one of these valves being provided ordinaril the building as may be desired or required. Each of the valves D has a valve shell D furnished with a valve seat d against which the valve D closes, and communicatingwby a branch pi e b with ahwate'r supply pipe.

The va ve D is automatically operated b 'iron core or p unger D of which is preferably secured directly to the valve. The solenoid D is contained in aclosed- 08.50 D connected. bv a screw plug or couplin' D with the valve shell D The spool the solenoid is preferably of brass and the case or shell D and plug D are referably of soft iron so as to serve as part 0 the magnet circuit. The spool D" is closed liquid ti ht at its lower end by a soft iron core '1) axed by a pin or screw D to the shell D which serves to cause the magnet to hold the movable core D with great ower in the open position of the valve, whi e at the same range of movement. The'solenoid coil D for o crating each valve D is connected in an e ectric circuit E havin othersource of power F an leading there through the coil. of a recorder magnet f thence to the coil D of the-solenoid, and thence back to the battery or other source of power. The valve circuit F is automatically closed by the relay 9, in a thermostat circuit G. Each of the thermostat circuits mostats g which operate to close the therperature in the room, or section of the buildmg where the thermostat is located, and thus closes the valve circuit F at therelay g and opens the valve D through the action of its operating solenoid. f

The thermostat circuit G leads from the battery F to the thermostat or thermostats 9 included therein, and thence through the The sprinkler pipes B are connectedwith a mostat circuit by an abnormal rise of tern-.-

relay 9 and thence back to thebattery or The system of water pipes B is furnished at intervals with a number of electromagnet for each room or floor or sectionof an electro-Ina met or solenoid D,,the so t" time the movable core is giventhemecessary a battery .or 1

from to the armature f of a relay 9 included in the thermostat circuit G, and thence G has included therein one or more the? Vmostat circuit by operatin source of power. 3 The relay g leads from the battery F or source of power left closed and thus shutting off the supply throu h the-relay h which operates the city fire a arm, thence through the fire alarm device h and thence to the armature f and back along the circuit wire F to the battery; To adapt the valve D to be also 0 ened by'hand, it is furnished with astem engaged'by a cam in on a rock shaft is operated by a hand lever K. A spring K returns the hand lever to its normal position against a "stop K. p

To able the .automatic electro magnet operat on of the valve 'to'be. tested without .fioodin the building or injuring its con-i tents, rovide a supplementa valve M having a iandle or lever M for closing the The valve 'M is preferably located 'just above the-valve D. hrough the valve shell M of the. valve M, I provide a small hc e m through which a small quantity'of water may escape when the valve -D is opened and the valve M closed. To uard against any possibility of the valve M emg of water from the sprinkler nozzle b when the valveD is'op'ehdd, I provide the system or apparatus witha test or? indicator circuit N havin one or more test or indicator devices N ancluded therein and which test cir- ,c'uit is opened by the valve M or its handle .when said valve is opened, arid which circuit 1 is, closed when he valve M is closed The -Q-test or indicator circuit N leads froth the battery or other source'of ower to a switch n,;,wh1ch is operated by't e turning of the -=.-valve M; *thence throu h the indicator dei "vice-N and thence bac to the battery.

One or mbre electro magnet valves D are located on'each floor of the building and in each room or section thereof as may be de-. sired, each controlling the su ply of. water to a set or series of rose-hea s or sprinkler nozzles 1). Each electro inagnet valve D has its own individual circuit F and thermostat "circuit G for automatically 0 enin and closing the same by the rise or all 0 temperature and each thermostat circuit G also has its own individual fire alarm circuit G and common/test or! indicator "circu t N and switchnso that-a firein any part of the building will automatically open the electro magnot valve, and its extiifiguishment, automatically close; the samefand so that the operativeness of 'each'el sctro magnet valve D may be independently-tested without injury to the building or itscontents by flooding.
